1 1 Claim.

The invention relates to the execution, on flat knitting machines withsinker bar of theCotton type, of unravelable edges according to themethod described by the applicant in his prior United States Patent No.2,313,294, dated March 9, 1943, which consists in that the row or onepart of the row of loops which it is desired to render unravelable issubmitted, when finished, to a transfer of every other loop by anamplitude of two needles, 1. e. on the needle following its neighbour,each needle having one loop and one out of two loops being transferredby two needles while the other loop is not transferred.

The invention relates more particularly to the execution, on each ofboth lateral parts of the sole entrance (that is to say of both parts ofthe beginning of the sole lying outside the instep or front part of thefoot), of the unravelable edge adapted for their later connection withthe tongues of the heel in the making of stockings, half-stockings orsocks with a French heel comprising the leg and the foot made in asingle operation on the frame.

The invention permits to effect this operation with simple means withoutany supplementary complication of this kind of frames by using, for thispurpose, and without modifying its system of transfer and of feeding,the narrowing attachment designated under the name of toe attachment" inthe frame with French foot.

The invention has for its subject matter improvements which consist. inthat one uses for the execution of the unravelable edge of the lateralsole entrance parts (or of the unravelable edge of any lateral partssymmetrically arranged in a knitted article), the transferring hook barsor combs of the toe attachment; in that the said bars which are, forthis purpose, set apart from the centre of the needle bed are arrangedso that in each pair the wide transfer comb and the narrow transfer combare in contact on their adjacent lateral faces, and in that each pair ofcombs is combined with a notched covering knife showing a notch oppositeone out of two transferring hooks on the transfer combs.

The invention will be better understood owing to the followingdescription of an illustrative embodiment thereof shown diagrammaticallyin the appended drawing, in which:

Figure 1 is a front elevational view of the device used for theexecution of the unravelable edge, and

Figure 2 is a side view of the same.

Referring now, more particularly to the drawings, I represents .theneedle bed with a fixed ance April 7, 1944 central part of a Cottonknitting machine and 2 the needles.

3 and 4 are the wide transferring hook bars or wide combs, of the toeattachment and 5 and 6 are the narrow bars or narrow combs of the saidtoe attachment; 1, 8, 9 and I0 are the flat rods on which said differenttransfer combs are screwed respectively; H are the transferring hooksand I2 are lateral covering knives, i. e. blades mounted, for instancepivotally, on an axis l3 so that they can be brought to insertthemselves at the desired moment between the transferring hooks II andthe needles 2. Said knives are notched so as to show a notch for everyone out of two transferring hooks, thus permitting the loops to be takenon every other needle.

In order to render unravelable the first course of the sole on thewidths Z corresponding to the lateral entrance parts of the sole, thetransfer combs 35 and 4-6 are set apart from the centre of the needlebed and brought to the position shown in Figure 1 without leaving anyspace between the adjacent lateral faces of the bars 3-5 and 64. Thelateral notched coverin knives l 2 are brought into the active positionand through the co-operation of the ordinary toe attachment with thenotched knives l2 one causes every other loop to be taken andtransferred from its needle to that following its neighbour,

this transfer taking place in the direction shown by the arrows, i. e.from the outside to the inside. Thus, one obtains a total symmetry.Furthermore, by judiciously selecting the needles on which the lateralknives l2 must act, any risk of transfer of loops outside the selvedgesis avoided. v

The axis l3 on which the lateral notched knives 12 are mounted can be asupplementary axis. It can also be the same as that of the ordinary toecovering knife l4. In this case, an angular shifting is provided betweenthe lateral notched knives l2 and the plain middle knife I4 so as topermit to bring them successively into the working position. For theexecution of the unravelable row, the lateral notched knives l2 are inthe working position and the middle knife 14 is behind the plane of theneedles, which is possible owing to the fact that there are, at thismoment, no transferring hooks opposite the knife l4. During theexecution of the toe, on the contrary, the transfer combs 3-5 and 64having been brought back to the centre, the middle knife I4 is in theworking position while the 3 lateral notched knives 12 are in front ofthe needles, which causes no interference.

I claim:

In a. knitting machine of the character described, in combination, aneedle bed, a frame, a toe mechanism onttheframe comprising two pairs oftransfer combs having transferring points, each pair including one widecomb and one narrow comb, the pairs of combs being spaced on" the framein such a manner'tha-tgforz'eachpair the lateral adjacent faces are incontact, andia notched covering knife coacting'vvith'narihioneajf v thepairs of transfer combs throughout the, length of both combs,each'kni'fefheingnotchedi so as to show a notch for every one out of twotransferring points, thus permitting'loopsito-be; taken on every otherneedle during the working of the unravelable edge of the lateralparts-of the sole entrance of stockings,
